In relation to the book 'Microsoft Windows Networking Essentials Book' (ISBN: 978-1-118-01685-5). There is a possible error on a page number 277. It is related to chapter 13 (Understanding Internet Access Methods and Wide Area Networks).
Refer to Table 13.5 (VPN tunneling protocols).
There are two errors in this table.
(a) In the row identified as 'PPTP' it states its port as 1701. This is incorrect.
The port should be stated as 1723 .
(b) In the row identified as 'L2TP' it states its port as 1723. This is incorrect.
The port should be stated as 1701 .
Do you agree in both cases?
